its service agent.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualied persons
to avoid a hazard.
• The rated voltage is 115V, and the rated frequency is 60Hz. If the working voltage is too low or too high, the compres-
sor may be damaged.
• Use a three-prong socket (grounded). For safety, ensure the socket and cord are rated for more than 10A. Always
ensure the socket is properly grounded. Do not modify the power cord or plug. Securely connect the plug and socket
to prevent re hazards.

Setup
• When unpacking, check to ensure all accessories are included. After verication, repack properly before transporta-
tion.
• During handling or transportation, avoid rough handling and shaking. The incline should not exceed 45 degrees to
protect the cooling system.
The appliance should be placed on a solid and level surface to ensure stability and safety.
• Do not place any items taller than 4 inches inside the showcase to ensure optimal operation and energy savings.
• Before connecting to electricity, remove the plastic cover from the plug. Ensure the appliance is running properly be-
fore placing food inside.
• Place the machine on a at and solid surface. If you need to raise the machine, use a at, solid cushion. Do not use
soft cushions or packing materials like foam or polystyrene underneath as a cushion.
• Avoid placing the machine in moist areas or where it could get wet or dirty. Clean it with a soft cloth as soon as possi-
ble to prevent mold and maintain insulation.
• Do not use the machine in very cold environments or outdoors in the rain.
• To ensure proper operation, do not place the machine under direct sunlight or near heat sources.
• Keep the machine in a well-ventilated position and open the door to allow air circulation.
• Although the machine is pre-cleaned at the factory, please clean it again before use.
• The machine should be empty when starting. Set the thermostat and connect it to electricity to begin operation. The
compressor may initially stop after a short period as the machine might be warm. Once the internal temperature
decreases, the machine will function automatically. It is recommended to wait for the internal temperature to lower
before placing items inside the showcase.

Operation
Temperature Set
• Press the “SET” button for 3 seconds until the set indicator lights up and the number on the LED display ashes. This
number indicates the current temperature. Press to adjust the number.
• The adjustable temperature range is 0°C to 10°C.
• The temperature setting will be conrmed if no buttons are pressed for 10 seconds.
Compressor Start Delay Time
• When powering on for the rst time or after a brief power outage, the compressor will delay for about 8 minutes be-
fore starting. This delay helps prevent compressor damage from frequent on/off cycling.
Illuminate
• Press the button to turn the lamp on. Press the button again to turn the lamp off.

Maintenance
Cleaning
• Before cleaning, always unplug the appliance.
• Use a soft cloth or sponge with clear water or mild soap.
• Do not use organic, alkaline, hot water, or acidic cleaners on the showcase.
• Avoid using water to clean the compressor area. After cleaning, use a cloth to dry any water to prevent rust.
• Ensure hot food is cooled before placing it in the fridge room to prevent damaging the cooling system.
• When placing food, keep a reasonable distance between items to ensure proper airow. Avoid blocking the cooling air
outlet and inlet to maintain cooling eciency.
• Do not frequently open the door or leave it open for long periods while the machine is operating. Keep the door closed
tightly to save energy.
• After a power outage, wait at least 5 minutes before turning the machine back on to avoid damaging it.
• If the internal temperature rises due to a power cut or other failure, it is recommended to stop using the machine until
it returns to normal.
• If the machine will not be used for an extended period, turn off and unplug it. Clean it thoroughly, and after drying, seal
it for storage.
• To prolong the machine’s lifespan, do not turn it off and on frequently. Wait at least 5 minutes between turning it off
and on again.
Defrost ice
• Normally, when the compressor stops, the body temperature will rise, causing the evaporator frost to thaw and drain
to the water box in the compressor room.
• The water in the box will evaporate due to the heat when the compressor is running, eliminating the need for manual
defrosting.
Replace the Lamp
• If the lamp is damaged, contact customer services. Do not attempt to replace the lamp yourself.
